1% OF NATIONAL PARK, NEW JERSEY, ASSIGNOR TO FURNESS COR- JPQMTTON, @E' rmr, PENNSYLVANIA, A CORPORATION OF NEW JERSEY CAKE $1 003 Application filed July 26, 19%. Serial No. 381,199.

This invention relates to cake spools and is especially useful for cakes of artificial silk thread.

The invention will be described in connec- 5 tion with cakes made of cupro-ammonium artificial silk thread, which cakes are subjected to a washing operation to remove the acid employed in the removal of the copper.

One or the primary objects of the invention 1 is to provide a spool which will very efiectively and uniformly subject the thread to the washing medium.

More specifically it is an object of the invention to provide means for protecting the thread while on such a spool.

lE accomplish the foregoing, together with such other objects and advantages as may hereinafter appear, or are incident to my invention, by means of a construction which ll have illustrated in the preferred form in the accompanying drawings, wherein- Fig. 1 is a side elevation of the complete spool with certain of the members thereof broken out to more clearly show the construction, and

Fig. 2 is a fragmentary view partially in section and drawn on an enlarged scale to illustrate certain features of the spool.

Referring now to the drawings, the referao ence character A designates the spool Which, in the main, has a s indle portion B and rims 7-7. This part 0 the s 001 is made of any suitable metal and the spindle portion is provided with a plurality of annular grooves 8.

Over the spindle is placed a screen 9, prefercomposed of a copper screening fabric,

hi and over the copper screen I provide a covering 10 of fabric such as cheesecloth, this covering being preferably continued up the so sloping sides of the rims 7.

The cake is laid on the cheesecloth, which keeps the thread out of contact with any metal.

The spool is preferably driven by rollers uponwhich the spool is placed and by which it is supported, and the wash water is usually applied in the form of a spray at the top of the cake. The cake is pervious and is preferably wound in the manner described in my copending application Serial No. 239,405, filed December 12, 1927 and since issued as Patent No. 1,770,397 on July 15, 1930. Wash water passes through the cake and through the foraminous cheesecloth and copper screen and enters the channels formed by the annular grooves 8 and the overlying copper screen and cheesecloth, running around the channels and passing out through the screen, cheesecloth and cake toward the bottom. Some of the wash water, of course, runs around on the outer periphery, particularly of the upper half, penetrates through the cake and into the channels and thence back through the screen, cheesecloth and cake, as above described.

Tn addition, the multiplicity of annular grooves keeps the water which enters the channels uniformly distributed across the spindle, so that there is uniform distribution of such water through the cake as it flows out of the channels and through the screen, cheesecloth and cake. The provision of such annular grooves also, in the first instance, tends to secure uniform flow, as it were, through the cake to the channels throughout the length or" the spindle,

The spool shown in about twelve inches in diameter and about six inches in length, and inFig. 2 the screen and the cheesecloth are shown in grossly exaggerated form.

I claim:

1. A spool for cakes of thread having plurality of annular grooves on its spindle portions and a "foraminous covering over said spindle portion upon which the thread is adapted to be wound.

2. A spool for cakes of thread having a plurality of annular grooves on its spindle portion and a foraminous covering over said spindle portion upon which the thread is adapted to be wound, said foraminous covering consisting of a. layer of copper screening and a layer of relatively pervious cloth.

3. A spool for cakes of thread having a spindle portion and rim portions, said pindle portion being provided with a multis p icity of annular grooves throughout its length and a foraminous covering over the spindle portion cooperating with said grooves to provide annular channels.

In testimony whereof I have hereunto signed my name.

WILLIAM H. FURNESS.
